Do the auditions start tomorrow as that is what I have read

and no xtra factor host CONFIRMED......

yes room auditions start tomorrow in Leicester

Simon has the flu and Dermot has food poisoning so looks like Rochelle might have to do the auditions and the panel to be Sharon-Louis-Nicole tomorrow if Simon and dermot are still ill

who will replace them?

Well I'm guessing the judges will be Sharon-Louis-Nicole if Simon is still ill and if dermot is still ill I'm guessing that Rochelle will cover and the other co host will do xtra factor on their own for the day.

Dermot announced on Twitter he will be going, not so sure about Simon though.
